Claims

[Scope of utility model registration request]

A piston that reciprocates within a cylinder, a piston ring fitted into a piston ring groove of the piston, and a piston ring that is extended in the radial direction of the piston to constantly press the piston ring against the inner surface of the cylinder. A compressor having a plunger for extending a piston ring, characterized in that the compressor is provided with a cushioning material provided at a portion where the plunger and the piston ring groove come into contact with each other due to the reciprocating movement of the piston to buffer the contact. Plunger shock absorber for compressor piston ring extension.
